TO ALL WHOM IT MAY CONCERN:

Be it known that I, GEORGE E. MOORE, of Lyons, in the county of Clinton,in' the State of Iowa, have invented certain new Improvements in Stoves;and I do hereby declare that the Following is .a full and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon.

The object of my invention relates to improvements in stoves in twoparticulars: first, a plan of constructing the top (by insulation) sothat it is capable of sustaining, without injury from the fire, artisticornaments in colors, and bronzelaid in japan and other varnishes;second, a plan for kindling the gas and coal above a considerableportion of the unburned coal, (bymeans of a doorway and passage into thesides of fire-chambers,) so as to secure a more constant and reliableflame for illumination than is usual in gas-burning stoves.

Figure 1 is a perspective viewof a coal-burning stove with myimprovements applied. A is the insulated top resting by thin edges, a aan, upon the separating plate B, which is mounted upon open work, {so asto allow a circulation of air below it,) and sustained by the ordinarytop of the stove 0, thus bringing the separating plate B to sustain thetop on points or thin edges, and preventing the conduction of heat fromthe fire to A in such force and quantity as to injure the ornamentalpaintings upon it, laitl'in japan and other varnishes. D is thefeed-door for supplying coal to'the fire-chamber. E is a door opening apassage to the coal in the the chamber, by which lzindiings may beintroduced and the gas and coal ignited. It is partly of mica.

Figure 2 is a perspective view of the internal arrangement. F is asmotherer or cover shut down upon the coal in the fire-chamber; the redlines show its position when turned off or up from the coal. G is thegrate, upon which the coal rests at the bottom of the fire-chamber. Eis, a diaphragm for sustaining the coal, to some extent, when thegrateis turned for emptying cinders, and to allow a space for theintroduction of kindlings above the grate from the front, I is a damperupon the outside 0? the fire-chamber for closing the passage out fromit, should it ever be desirable to do so, to put out the flame and tocheck combustion at that point. It is shown open in fig. 4:, where alsothe red lines indicate its position when closed. 'A draught from I tothe smoke pipe K is obtained between the fire-chamber and the outsidecasing from I to J. J is a damper in the flue where it is placed; theredlines show its position when open. K is the smoke pipe.

Figure 3 is a vertical view of the inside arrangement with all thedampers open. The red lines show the position of dampers when closed.

. Figure 4 shows a front view of the dampers I and J.

Figures 5 and 6 show the mode here used in insulating the top A.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The insulation of the tops of heating stoves, substantially inthemanner and for the purposes set forth.

52,- I claim the chamber in front part of-the stove, between the door Eand upper part of plate H, when construoted'and arranged as and for thepurposes set forth.

I claim the flue from the fire-chamber through the front upper chamberto chamber in top of the stove, with the controlling dampers, arrangedsubstantiallyas and for the purposes set forth.
